because Ubuntu on Sheevaplug is not supported, I decided to update my Sheevaplug to Debian Squeeze, on the NAND. I use the restore procedure to do that. This method only works with Globalescale, Ionics has different rootfs ! This method also updates the Sheevaplug to the current last kernel, 3.4.5.

after few minutes, and some restart, you'll have a UBIFS system, with Linux kernel 3.4.5 (currently the last update in August 2012) with Squeeze Debian.The root password is always : nosoup4uThe directories /tmp and /var/log are tmpfs system. You can check them by the command df: df Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 256620 0 256620 0% /lib/init/rw udev 10240 112 10128 2% /dev tmpfs 256620 0 256620 0% /dev/shm rootfs 472968 167008 301124 36% / tmpfs 256620 0 256620 0% /tmp tmpfs 256620 84 256536 1% /var/logYou can update the file /etc/fstab with this line (no set access time to file, to not write always on NAND) rootfs / rootfs rw,noatime,sync 0 0If you have a proxy, you can create the file /etc/apt/apt.conf with these lines for example: Acquire::http::proxy "http://myproxy:1234/"; Acquire::ftp::proxy "http://ftp://myproxy:1234/"; Acquire::https::proxy "https://myproxy:1234/";You can add softwares with apt-get command, but don't use the upgrade command. Because it wants to updateyour kernel in 2.6.32 (August 2012), while you have a 3.4.5 kernel.

These updates will be done at your own risk. I decline all damages which can arrived during theupdate.
